Whister? I haven't heard that name in a while. It was the original code name for Windows XP while it was in testing stage.
You can go to the root of your C drive or whatever drive you installed XP on, and ope the boot.ini file (you need to be able to see hidden files and protected operating system files. Go to folder options). It shoud look like this if you have XP pro SP1 on one drive (C drive) and on the first partition:
You should be able to delete anything else. If you cannot edited te file, then open it and copy it's contents, then move it and create a new boot.ini file where it once was, and paste the contents into the new file. You can edit it then.
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
If for whatever reason, you cannot boot your system, use this tool EditBINI. It allows you to edit the file without Windows. It is included in The Ultimate Boot CD
